我试图在下面的代码的每个for循环中更改要写入的日志文件。但是，由于日志文件名尚未更新，因此在第二个循环结束时出现了错误。
我需要更改我的代码吗？
from datetime import datetime
import logging
master_list = ['1']
for fr_var in master_list:
logfile1 = '{}{}_{}.{}'.format('G:\\Python27\\Test\\', 'Export_Logfile_', datetime.now().strftime("%Y%m%d%H%M%S"), 'log')
logging.basicConfig(level=logging.INFO,
format='%(asctime)s - %(name)8s - %(levelname)5s - %(message)s',
filename=logfile1,
filemode='w')
logging.captureWarnings(True)
log = logging.getLogger(__name__)
log = logging.getLogger() # root logger
for hdlr in log.handlers[:]: # remove all old handlers
log.removeHandler(hdlr)
logging.shutdown()
with open(logfile1, 'r+') as f:
content = f.read()
f.seek(0, 0)
f.write('=============================================================')
print('test')
f.write('=============================================================' + content)
for fr_var in master_list:
logfile2 = '{}{}_{}.{}'.format('G:\\Python27\\Test\\', 'Import_Logfile_', datetime.now().strftime("%Y%m%d%H%M%S"), 'log')
log.addHandler(logfile2)
logging.basicConfig(level=logging.INFO,
format='%(asctime)s - %(name)8s - %(levelname)5s - %(message)s',
filename=logfile2,
filemode='w')
logging.captureWarnings(True)
log = logging.getLogger(__name__)
log = logging.getLogger() # root logger
for hdlr in log.handlers[:]: # remove all old handlers
log.removeHandler(hdlr)
logging.shutdown()
with open(logfile2, 'r+') as f:
content = f.read()
f.seek(0, 0)
f.write('=============================================================')
print('test')
f.write('=============================================================' + content)
错误：
Traceback (most recent call last):
File "G:/Python36/Test/Test.py", line 69, in <module>
